8. Questions to Ponder… Why would girdling, the removal of bark and vascular cambium in a narrow ring all the way around a tree, result in the death of a tree? If you remove the apical meristem from a dicot plant, what would be the effect on further plant growth? Of what value are tubers, a type of stem modification, to the survival of a plant species?

9. Root Tissues: Closer Look Brainstorm: If you were to design the perfect root system for a plant, how might it look like? --spidery for increase surface area --longer, to draw more nutrients and water, more spread out with less competition for resources. --sturdy to survive tough weather

17. Root Tissues: Closer Look How does water pass through to get into root for transport? Symplastic Route (class exchange): Apoplactic Route (going through hall ways): Epidermis  endodermis  pericycle or cambium  xylem

19. Root Tissues: Closer Look The Hydrogen Pump http://highered.mcgraw-hill.com/olc/dl/120068/bio05.swf (1)Uses Active transport (ATP) to move the proton (hydrogen ions) from the cytoplasm To the lysoome (or one area to another) (2) The protein changes shape to bring H ions through: The protein is conformation A When it receives an ion. Under ATP, it turns to conformation B to release the ion to the Other side.
